Impact of COVID-19 pandemic on specialty training in obstetrics and gynaecology in Hong Kong: is there a concern about the future prospect?

Introduction: The COVID-19 pandemic in the past few years led to major adjustments in the provision of healthcare. This study aimed to investigate trainees' perception of impact of the pandemic on specialty training in Obstetrics & Gynaecology (O&G) in Hong Kong.

Methods: A cross-sectional questionnaire survey was performed on all the O&G trainees and the young fellows of the Hong Kong College of Obstetricians and Gynaecologists (HKCOG).

Pregnancy and perinatal outcomes of women with SARS-CoV-2 infection during pregnancy.

Introduction: This study aimed to compare the pregnancy and perinatal outcomes of women with and without severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during pregnancy.

Methods: Women who delivered in an obstetric unit from March 2022 to October 2022 were recruited. The history of vaccination and SARS-CoV-2 infection during pregnancy was recorded.

A prospective study on neonatal ophthalmic injuries associated with forceps delivery.

Background: Assisted delivery by forceps is needed to expedite vaginal delivery in certain maternal and fetal conditions. The aim of this study was to evaluate the incidence and the extent of ophthalmological injuries in neonates after forceps delivery.

Methods: Women with cephalic fetuses delivered vaginally by forceps from July 2020 to June 2022 were recruited prospectively.

Precision of vacuum cup placement and its association with subgaleal hemorrhage and associated morbidity in term neonates.

Purpose: To evaluate whether the precision of vacuum cup placement is associated with failed vacuum extraction(VE), neonatal subgaleal hemorrhage(SGH) and other VE-related birth trauma.

Methods: All women with singleton term cephalic fetuses with attempted VE were recruited over a period of 30 months. Neonates were examined immediately after birth and the position of the chignon documented to decide whether the cup position was flexing median or suboptimal.

Prenatal Diagnosis and Pregnancy Outcomes of Fetuses With Orofacial Cleft: A Retrospective Cohort Study in Two Centres in Hong Kong.

Objective: To evaluate the local incidence of orofacial cleft (OFC) encountered in fetal morphology scan and prenatal diagnosis, genetic etiology of fetuses with or without other structural abnormalities, and their pregnancy outcomes.

Design: Retrospective cohort study.

Setting: Two maternal fetal medicine units, tertiary hospitals, Hong Kong.

Trend and causes of maternal death, stillbirth and neonatal death over seven decades in Hong Kong.

Background: Reducing maternal and perinatal mortality is a global objective. Hong Kong is a city with low maternal and perinatal mortality but little is known about the trend and causes of these deaths in this high-income city. We analyzed the maternal death, stillbirth and neonatal death since 1946 in Hong Kong.

The Discriminant Use of Intrauterine Balloon Tamponade and Compression Sutures for Management of Major Postpartum Hemorrhage: Comparison of Patient Characteristics and Clinical Outcome.

Background: Intrauterine balloon tamponade (IUBT) and compression sutures have been widely used in recent years in the management of postpartum hemorrhage (PPH). However, there is scant literature directly comparing the clinical scenarios that led to the discriminant selection of these management modalities and the direct clinical outcomes. The purpose of this study is to compare the patient characteristics and clinical risk factors that led to the use of IUBT and compression sutures in the management of major PPH as well as the immediate outcome in a retrospective cohort.

Use of balloon tamponade in management of vaginal laceration and its possible complication of urinary stress incontinence: a case report.

Background: Postpartum haemorrhage from vaginal lacerations can occasionally be refractory to suturing and vaginal packing. Bakri uterine balloon has been widely adopted to stop uterine bleeding, but its use to stop bleeding in vaginal lacerations and its possible complications have seldom been reported.

Case Presentation: We report a patient who had vacuum delivery for fetal distress and subsequently had postpartum hemorrhage due to previous caesarean uterine scar rupture and multiple vaginal lacerations.

Risk factors for severe postpartum haemorrhage during caesarean section for placenta praevia.

The objective of this study was to evaluate the value of clinical and ultrasound risk factors in predicting severe postpartum haemorrhage (PPH) (≥1.5 L) in pregnancies undergoing caesarean section for placenta praevia. This cohort consists of all cases of placenta praevia undergoing caesarean delivery over a period of 5 years in a service unit.

Comparison of the accuracy of INTERGROWTH-21 formula with other ultrasound formulae in fetal weight estimation.

Objective: A new ultrasound formula for fetal weight estimation was proposed from the INTERGROWTH-21 project in 2017. There is no comparison of its accuracy with other ultrasound formulae. This study aims to compare the accuracy of INTERGROWTH-21 formula in fetal weight estimation with the traditional Hadlock1 and Shepard formula.

Menstrual and reproductive outcomes after use of balloon tamponade for severe postpartum hemorrhage.

Background: The use of intrauterine balloon tamponade to manage postpartum hemorrhage is increasing. However, there is lack of studies on the menstrual and reproductive outcomes after such treatment. The purpose of this study is to explore the menstrual and reproductive outcomes for patients who had been managed by intrauterine balloon tamponade for severe postpartum hemorrhage in her index pregnancy.

Outcome of pregnancy with new onset proteinuria and progression to pre-eclampsia: A retrospective analysis.

Objective: To examine maternal and neonatal outcomes of gestational proteinuria, and to identify maternal characteristics for progression to pre-eclampsia.

Study Design: Retrospective cohort. Included all pregnant women who delivered between Jan 2014-Feb 2017 with new onset proteinuria in a single obstetric unit.

The predicting factors and outcomes of caesarean section of the second twin.

The aim of this study was to review the indications for caesarean delivery of second twins after vaginal delivery of a first twin (combined delivery) and the associated foetal outcomes of the second twin. Possible factors that could be employed to predict combined delivery were explored. This was a retrospective review of all twin pregnancies delivered in a tertiary maternity unit between 2000 and 2013.

Neonatal outcome and mode of delivery in the presence of nuchal cord loops: implications on patient counselling and the mode of delivery.

Purpose: To review and compare the foetal outcomes and mode of delivery in patients with nuchal cord for single loop, double loops, and multiple loops.

Methods: A retrospective study of 4,404 singleton term pregnancies which underwent spontaneous labour was conducted. The patients were classified into five groups: without nuchal cord, nuchal cord of any turns, nuchal cord for 1 turn, nuchal cord for 2 turns and nuchal cord for 3 turns or above.
